The Oral Health and Swallowing Research Lab

Welcome to the homepage for the Oral Health and Swallowing Research Lab housed in the School of Communication Sciences and Disorders at Dalhousie University. We use an interprofessional focus to explore the interrelationships between oral health, swallowing, and other factors such as frailty.

The Lab

Current Projects

We conduct collaborative and impactful research focused on improving the oral health of older adults. We are currently working on several projects that investigate the impact of oral health and swallowing on quality of life, and social vulnerability. You can learn more about the work we do here.

Dysphagia and Oral Health Concerns in Long-Term Care

Swallowing impairment, or dysphagia, is highly prevalent in older people living in long-term care, as are oral health concerns such as missing teeth and periodontitis. Texture-modified diets are frequently prescribed for long-term care residents to manage concerning oral health conditions and dysphagia, but their use is associated with increased risk of malnutrition, dehydration, and reduced quality of life. This survey study was conducted to explore the knowledge and perspectives of long-term care staff pertaining to swallowing disorders, oral health, texture-modified diet use, and barriers and facilitators to identifying and advocating for swallowing and/or oral health assessments for long-term care residents. The survey was developed with input from an advisory panel and refined through two rounds of Delphi-method polling. The survey was administered to staff working in long-term care facilities in roles that involved face-to-face contact with residents in the provinces of Ontario, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador. Complete responses were obtained from 148 participants who primarily reported working as nursing assistants, health care aides, or personal support workers in Nova Scotia and New Brunswick. The results suggest that frontline long-term care staff may have limited knowledge of swallowing disorders, and overreliance on texture-modified diets is likely. Instrumental swallowing evaluations and professional oral health assessments appear to be rarely accessed. Speech-language pathologist involvement on longterm care interprofessional teams could be beneficial for educating staff, providing comprehensive management of swallowing impairments, and curbing the overuse of texture-modified diets in longterm care.

Our lab is located in Kjipuktuk (Halifax), situated within Mi’kma’ki (Nova Scotia), the ancestral and unceded territory of the Mi’kmaq People. As we work and learn on this territory, we pay respect to the Indigenous knowledge held by the Mi’kmaq People and to the wisdom of their Elders, past and present.


We recognize that African Nova Scotians histories, legacies, and contributions have enriched Mi’kma’ki for over 400 years. Being situated in Kjipuktuk, we acknowledge the historical injustices faced by the community of Africville who was forcefully displaced in the 1960s.
